Rule Set:rulesets/java/sunsecure.xml/ArrayIsStoredDirectly
Description:
False positive for ArrayIsStoredDirectly when defensively copying an array (manually) and using the this keyword to refer to the instance variable.
Code Sample demonstrating the issue:
public class Foo {
private final int[] a;
public Foo(int[] b) {
this.a = new int[b.length];
for (int i = 0; i < b.length; i++) {
this.a[i] = b[i]; // triggers ArrayIsStoredDirectly
a[i] = b[i]; // no warning
this.a[i] = b[i]; // triggers ArrayIsStoredDirectly
}
}
}
Running PMD through: CLI
pmd-bin-5.7.0/bin/run.sh pmd -d . -rulesets java-sunsecure
